A proper pool closing in Connecticut and New York is essential. Freezing temperatures can crack plumbing lines, split pump housings, and destroy heater components when water is left in the system. This checklist covers everything a complete winterization should include.
When to Close Your Pool in CT and NY
Close your pool before overnight temperatures drop below 32 degrees Fahrenheit consistently, typically mid-October in Fairfield County and Westchester County. Waiting too long risks a freeze event catching you off guard.
Water Chemistry: One Week Before Closing
- Test and balance pH to 7.2 to 7.6
- Adjust total alkalinity to 80 to 120 ppm
- Shock the pool with a high dose of chlorine
- Add winter algaecide per label directions
- Add a metal sequestrant if your water has iron or copper
Equipment Shutdown
- Turn off and unplug the pump, filter, heater, and automation system
- Drain water from the pump, filter, heater, and chlorinator
- Remove and store the pump strainer basket and cartridge filter elements
- Backwash DE or sand filters and drain completely
- Remove and store any in-line chlorinators or salt cells
Blowing Out the Plumbing Lines
- Lower water level 12 to 18 inches below the skimmer for mesh covers
- Blow out all return lines, skimmer lines, and main drain lines with a blower
- Install winter plugs in all returns, skimmer, and main drain
- Verify all plugs are seated. Water in any line will freeze and crack it.
Accessories and Cover
- Remove ladders, handrails, diving boards, and slides and store indoors
- Remove and store skimmer baskets, return eyeballs, and other fittings
- Install and secure winter cover with no gaps where debris can enter
- Add water tubes or cover anchors to keep the cover secure through winter storms
